Partial Hospitalization Programs provide intensive outpatient care for adults with mental health, trauma, or substance use concerns, using therapies such as CBT, DBT, EMDR, and family therapy.
Intensive Outpatient Programs provide structured treatment at a lower level of care than residential or partial hospitalization programs, with therapies tailored to individual mental health needs.
A self-assessment cannot diagnose agoraphobia, but it can help you recognize patterns worth discussing with a clinician, such as avoidance, distress in public settings, or fear of being unable to access help. Alter Behavioral Health uses evidence-based approaches, including CBT, DBT, EMDR, family therapy, and individualized care planning, to support adults seeking mental health treatment in Southern California and nationwide.

Agoraphobia may involve intense fear or anxiety about situations where leaving could feel difficult or help may seem unavailable. People may avoid public transportation, open or enclosed spaces, crowds, being outside alone, or being away from home. A self-assessment can help you notice patterns, but only a qualified mental health professional can evaluate symptoms and determine whether they fit agoraphobia or another condition.
